| Abstract | The effect of crystal orientation on the hot corrosion behaviors of Ni-based single-crystal (SC) superalloys exposed to mixtures of 90 wt% Na2SO4 + 10 wt% NaCl at 750 degrees C for 200 h were studied using the "deposit recoat " method. The results showed that the mass gains of the specimens with different orientations increased in the order of (210) < (100) < (110). The (210)-oriented specimen exhibited superior hot corrosion resistance, which resulted in the lowest mass gain. First-principles calculations indicated that the origin of the orientation-dependent hot corrosion resistance was the different diffusivities of active cations in differently oriented alloys. |
